nvTrust: NVIDIA Confidential Computing Ancillary Software

nvTrust is a repository which contains much of the utilities & tools, open-source code, and SDKs leveraged when using NVIDIA solutions in trusted environments, such as Confidential Computing.

For more information, including documentation, white papers, and videos regarding the Hopper Confidential Computing story, please visit docs.nvidia.com/confidential-computing/index.html

Early Access Considerations

This branch of nvTrust is currently considered General Access.

This software release features a software stack targeting a single H100 GPU in passthrough mode with a single session key for encryption and authentication and basic use of the Developer Tools.

Code and data will be confidential up to the limits of the NIST SP800-38D AES-GCM standard, after which the VM should be restarted, which causes a fresh session key to be created.

Release Notes

  • Hopper Confidential Compute early access features are supported on NVIDIA Driver Version 550 and later only
  • Release Notes may be found here.

License

The license for this repository is Apache v2 except where otherwise noted.
